摘要:

α-Galactosidase activity has been assayed using 4-methylumbelliferyl-α-galactoside as substrate in 66 amniotic fluid samples obtained between the 10th and 41st week of gestation. The mean activity decreases slightly between the 10th and 29th week from 2 to 1.4 mU/g protein and then rises rapidly to 8.2 mU/g protein near term. The α-galactosidase assay of amniotic fluid may be used as an indicator of the 33rd week of gestation.
